Hi everyone,
A few months ago, I purchased 2 vintage early LCWs, calico ash finish, 5-2-5 screw configuration. They're beautiful, but they came with the backrests detached and in need of new shock mounts to to reattach. I'd read a few DIY articles online, so I thought with the new mounts and epoxy purchased from Special K on eBay, I'd be good to go. (Seats are fine. Shock mounts show some wear, but don't need replacing yet.)
Here's where the trouble starts. I've replaced the mounts 2 to 3 times, and they just. will. not. stick. The wood surface has been cleaned, sanded, cleaned, sanded, wiped with alcohol, and so on. I've applied plenty of epoxy, carefully removing excess, and clamped them for 4 days before removing. My husband and I carefully sit on the chairs, and they're fine for a bit, then inevitably, the mounts pop off of the wood.
What gives?? Are these chairs only to be admired, and not sat in? Is there an online how-to I haven't seen?
Any help would be much appreciated! I love these chairs, but need legitimate secondary seating in our living room.
Thank you!

Make sure that the surfaces being
glued are clean, free of grease, oil, wax, and
other contaminants that could act as release
agents. If the surface is coated with cured
epoxy or other adhesive, sand before gluing and wipe the dust off.
Do not over clamp. Epoxy resins
require only contact pressure. Over clamping
can squeeze most of the adhesive out of the
glue joint and the epoxy that is left may be
absorbed if the surface is porous, starving
the joint. A glue-starved joint is very weak.
Use only enough pressure to hold the joint
immobile and keep the two surfaces in
contact until the epoxy has set overnight
at normal temperatures. Small clamps
tape, or rubber bands, can all be
utilized to do this holding job.
Cordially,
